Maytag Microwave shuts off after a few seconds

When your Maytag microwave shuts off after a few seconds, the most likely cause is an intermittently failing door switch. Inspect the primary, secondary, and monitor switches for overheating, arcing, or burning, then test each switch for continuity with a multimeter. A failing micro switch can cause the same symptom, including a microwave that stops after 3 seconds or turns off after a few seconds. If the switches test good, the main control board may be at fault, but control boards are often misdiagnosed, so check the switches first. Next, test the touchpad and control panel. If some buttons respond while others do not, replace the touchpad and control panel. A defective touchpad alone is less common, but it can make the microwave run briefly and stop when the display works and only certain buttons respond. If all other parts check out, replace the control board. Enter your Maytag microwave model number to find the exact replacement part for your appliance. Any repair that requires opening the outer cabinet must be performed carefully because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. Properly discharge the capacitor first, or hire a qualified technician if you are unfamiliar with that procedure.

01 - Maytag Microwave Door Switch

A door switch might be failing intermittently. Check each of the door switches for signs of overheating, arcing, or burning. If you don’t see any obvious signs of failure, use a multimeter to test each switch for continuity. If any of the switches is visibly damaged or only has intermittent continuity, replace it.

Highly Likely

05 - Maytag Microwave Touchpad

If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don’t, the problem is with the touchpad.
Highly Likely

06 - Maytag Microwave Control Board

Control boards are often misdiagnosed—before replacing the control board, first check more commonly defective parts, particularly the door switches. If all of the other components are working properly, replace the control board.
